Title: Solid-state image pickup element
Inventor: NISHIZAWA SHIGEKI
IPC: H04N5/341
Filed: 1989-10-02
Abstract: PURPOSE:To eliminate the accumulation of an unrequired electric charge and to prevent a video signal deteriorating by continuing to keep prescribed potential after turning on a switch for reset, and starting the signal accumulation of an optical diode setting the switch at an off-state by a selection circuit for sensitivity control when it enters an effective accumulation period. CONSTITUTION:When a pulse VEL1 corresponding to a horizontal gate line HG11 is set at a high level by the operation of an E/E (for sensitivity control) vertical shift register, a MOSFET Q9 is turned on, and a timing pulse VD1 is supplied to the gate of a MOSFET Q7. The potential of the horizontal gate line HG11 falls down to a low level by fixing the source potential of the Q7 at the low level as the ground potential of a circuit. MOSFETs Q1 and Q4 for reset are turned off corresponding to the change of the horizontal gate line HG11 to the low level, and photodiodes D1, D2 start signal accumulation operations. Therefore, since no accumulation of the unrequired electric charge is performed, it is possible to prevent the video signal deteriorating according to the discharge of the unrequired electric charge.

Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To facilitate the previous setting up work as well as relieving the shock to a chip at the time of clamping the chip in a die bonding device. SOLUTION: After once stopping a tool 1 at the stand-by position separating the tool 1 by a specific length L so as to clamp a chip 2 (a), a push-up pin 3 is lifted up so as to press the chip 2 against the tool 1 stopped at the stand-by position (b).

Title: Ignition timing controller for internal combustion engine
Inventor: MURAO YOSHINORI
IPC: F02P5/15
Filed: 1994-10-24
Abstract: PURPOSE: To always perform ignition in the optimum position so as to improve a starting characteristic by setting ignition timing at a start separately from ignition timing on the basis of throttle opening. CONSTITUTION: For separately setting ignition timing at a start on the basis of throttle opening, it is determined whether it is a start or not in 101, and if it is not a start, advance to 102 is made and an exciting angle is controlled. In 107, ignition timing is outputted. If it is a start, ignition timing synchronizes with rising of a REF signal so as to raise an ING signal, and ignition is carried out after setting ADVTST on the basis of lowering of the REF signal. In other words, advance to 103 is made for controlling ignition timing at a start, and in 104, if the ADVTST is set less than a certain value A by the throttle opening advance to 105 is made and ignition timing is selected on the basis of water temperature.  If the throttle opening is more than the certain value A, advance to 106 is made, and ignition timing is selected from another table on the basis of water temperature. The value selected in 105 or 106 is advanced to 107, and then, ignition timing is outputted. In this way, the optimum ignition timing can be set.
